Conclusions Analysis of prior drought scenarios suggests at approximately a 1-in- 4 chance that springflow at Comal Springs will fall below 30 cfs by late summer, and a 1-in-3 chance that they will fall below 60 cfs Without above normal rainfall, we can expect J-17 water levels to decline 10 to 20 feet by late summer, making Stage IV likely and Stage V possible Critical period withdrawal limits and average or better rainfall will help to reduce the amount of decline The chances that we will end the year above Stage II restrictions are about 1-in-4 The chances that we will end the year above Stage I restrictions are about 1-in-8 11
